7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not turn on. | No power to the USB port. Faulty USB cable. Fan malfunction. | Try a different USB port or power adapter. Use a different USB cable if available. Contact customer support if the fan remains unresponsive. |
| Fan is noisy or vibrating excessively. | Dust buildup on blades. Loose silicone feet. Fan placed on an uneven surface. | Clean the fan blades and grilles. Ensure silicone feet are securely attached. Place the fan on a flat, stable surface. |
| Insufficient cooling. | Incorrect fan placement. Obstruction of airflow. Excessive heat source. | Adjust fan position to optimize airflow (e.g., direct air towards hot components or exhaust hot air). Ensure no objects are blocking the fan's intake or exhaust. Consider using multiple fans or a larger cooling solution if the heat source is too intense. |
